Abstract of the Disclosure There is disclosed a vacuum switch of the type comprising two cup- shaped contact elements. Each comprises a carrier member having a circular base portion and an upstanding wall portion and an annular contact member located on the end of the wall portion remote from the base portion. The wall portion is divided into a plurality of segments by radial slots running obliquely with respect to the axis of the contact member. According to the present invention the carrier members are made from copper, either with or without an admixture of chromium and the annular contact member is made from a chromium-copper matrix, either with or without admixtures. The electrical conductivity of the contact member is less by at least a factor of three than that of the carrier member.
